Hello, I have Nintendo 3DS XL which has broken slot for cartridge, also outer camera is not working so I can't use physical copy of games and flashcards. I have tried to use rxTools v2.6 on my 3DS with firmware 7.1.0-15E. I did downgraded MSET to 4.x, but after applying rxinstaller.bin I can't use "Nintendo DS Profile" in System Settings because only it crashes and then 3DS reboots with information: "An error has occured, forcing the software to close. The system will now restart. (Unsaved data may be lost.)" Is it because of my firmware or what? I did NAND backup but after downgrading MSET to 4.x and before applying rxinstaller.bin. What I did wrong and what's the next possible step to fix this? Thanks in advance. Edit: I'm out of ideas. I've tried to apply my backup but nope, NAND.BIN error despite having this NAND backup on the root of SD card.
